I added the peeringdb link on the left which works fine, but also tried adding a second link on the right, which still has the peeringdb link even though it has a different value.

links:
- order: 0
show_icon: true
side: left
title: PeeringDB
url: https://www.peeringdb.com/asn/{primary_asn}
- order: 5
side: right
title: Website
url: https://google.com

I replaced the website with a generic one since this is my private github account :)
